Which is especially cool if you created an "old" (as the Debian installer calls it) ext2-fs and later add the journal and thus convert it to ext3. Because that way you can still use 2.0-kernel - based tools like tomsrtbt (<http://www.toms.net/rb/>) for, say, disaster recovery. All my filesystems are "upgraded" ext2 for exactly that reason and I have yet to regret that decision. >AFAIK the other systems are not in any way compatible/interchangeable >with others.
